The Russian Defense Ministry said earlier in the day that the two top military officials had very constructive negotiations dedicated to the humanitarian situation in Syria and bilateral cooperation.

The statement said the two ministers discussed regional security issues, including the latest developments in Syria.

"Special attention has been paid to the rapid resolution of humanitarian issues in Syria and the return of the refugees to their country," it said.

Mutual cooperation in the defence sector was also discussed, the statement said.

Akar and Fidan arrived in Moscow earlier on Friday, after which they participated in a welcoming ceremony, and held talks with Shoigu and other officials, the Anadolu news agency reported.

Issues related to mitigating the humanitarian crisis caused by the war in Syria once again became pressing after Syrian government forces regained control over the majority of its territory from terrorists, prompting thousands to begin their return home.
